- the amount of included within the base friction material includes between about 8% to about 30% by weight of final composition, more preferably between about 10% to about 25% and highly preferably between about 12% to about 20% by weight. In general, amounts below 8% by weight give rise to a relatively weak material and in contrast weight percentages over about 30% affect the acceptable porosity and anti-fading properties of the friction material.
- the inert fillers of the present invention are typically present in the range of between about 5% to about 20% by weight of the final composition. Under a more preferred embodiment the range is between about 7% to about 16% by weight, and, under a highly preferred embodiment the range is between about 8% to about 14% by weight of the final composition. While a number of commercially available inert fillers are useful under the present invention, barytes, clays, whiting and talc have proven to be particularly useful.
- the amount of carbon utilized under the present invention ranges from between about 6% to about 30% by weight. Under more highly preferred embodiments this range is from about 10% by weight to about 25% by weight, and under the most preferred embodiments this range is from 12% to about
- fibrous materials are also included within the composition of the present invention.

- the amount of fibrous material utilized in accordance with the teachings of the present invention ranges from about 10% to about 65% by weight of the overall composition. Under more preferred embodiments this amount ranges from about 20% to about 50% and under highly preferred embodiments the amount of fibrous material utilized will typically range from about 30% to about 45% by weight of the overall composition.
- the various iron powders which are useful in preparing the friction material of the present invention those known as LD-80, P100 and R12 which are available from Pyron, Inc. of Niagara Falls, New York have proven to be particularly useful.
- the iron metal powder utilized will have a particle size ranging from between about 35 and about 325 mesh, as tested under a common mesh screen analysis.
- the iron powder included within the base friction material is generally present in an amount between about 10% to about 35% based on the overall weight of the composition. More preferably, the amount of iron powder utilized in the base friction material is from about 12% to about 30% and still more preferably from about 15% to about 25% based on the total weight of the final friction material composition.
- a metal sulfide-iron powder alloy is formed by conventional alloying techniques and added to the base friction material to complete the composition.
- MP37R which is available from DOMFER Metal Powders, Ltd. of Montreal, Quebec, Canada has proven to be particularly useful.
- the metal sulphide-iron powder utilized will have a particle size of between about 60 and about 325 mesh, as tested under a common mesh screen analysis.
- This metal sulfide-iron powder alloy is typically present in an amount of between about 1% to about 15% based on a total weight percentage of the final composition. Under preferred embodiments this amount is typically in the range of between 2% to about 12% and under highly preferred embodiments from between about 3% to about 8% by weight of the final composition.
- the method of manufacturing a friction bearing component such as an automotive vehicle brake pad using the compositions according to the teaching of the present invention involve a conventional manufacturing process known as compression molding. Initially, the base friction materials including the fibrous materials, carbonaceous materials, inert fillers, iron powder and resin type powdery binders are admixed under continuous stirring within the mixing vessel. Subsequently, the metal sulfide-iron powder alloy is added to the base material and the overall composition is thoroughly mixed. Once the composition is fully mixed an amount of the material sufficient to mold the desired component is pre-shaped by molding under a pressure of approximately 150 kg/cm 2 at room temperature within a press mold.
- the preform molded product is further molded by subjecting it to pressure of 400 kg/cm 2 at a temperature of approximately 150 C C for approximately 8 minutes. Finally, the molding is released from the die and heated for approximately 12 hours at a temperature of 180°C. After the heated molding cools to approximately room temperature and any necessary final machining and assembly is done, the component may be applied to the automotive vehicle.
- the incidence of objectionable noise increases as the test progresses. That is, the lower noise rating values (i.e. more noise) are usually recorded towards the end of the test. While average noise ratings are shown, the inclusion of the metal sulphide-iron alloy in the formulation suppresses the rate of increase in objectionable noise incidence with time, as evidenced by the smaller difference between the average and worst noise recorded for those formulas containing the metal sulphide-iron alloy as compared with those formulas where the metal sulphide-iron alloy is absent.
